A major advantage with a longer trailer also is weight distribution!! More room to move the vehicle or load forward or back so it pulls properly, load to far ahead and it will buck like a bull over bumps on highway
And too far back and it will sway back and forth and become very dangerous, a longer trailer gives you the ability to
Load it facing forward or backwards, depending on the situation.
Just my view, I've been pulling trailers of every configuration for over 20yrs.
